Loom.

Application med January 14, 192i. seal No. 437,279.

To all whom it may concern.'

Be it known that I, JOHN T. FrrZPA'rRIcK, a citizen of the United States, residing at Cove, in the county of Polk, and State of Arkansas, have invented new and useful Improvements in Looms, of which the following is a specification. Y

This invention relates to looms, and the principal object of the invention is to provide means for reciprocating the bobbin- In describing my invention in detail,v

reference will be had t0 the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and 1n which:-

Figure 1 is a longitudinal sectional view, showing a part of a loom constructed in accordance with my invention.

Figure 2 is a longitudinal sectional view with the parts in a position to release the bobbin.

Figure 3 is a diagrammatic view showing how the carrying member and bobbin pass through the warps.

Figure 4 is a section on line 4 4 of F igure 2.

In these views, the frame of the loom is indicated at 1, and 'slidingly mounted on the lay 1 of said frame is a pair of carrying members 2, one of which is located at each side of the loom. Each member comprises a 4body 3 and a stem 4, said stem receiving the bobbin 5. The stem 4 is slidably mounted in a recess 3 in the body and is normally held in its outer position by the spring 3 which is located in said recess. A pin 3", passing through the stem and engaging the slots in the body, acts to limit the movement of the stem. Each oi' the members is reciprocated by means of the endless belt 6 which passes over the rollers 7, one of which is driven in any suitable manner. The endless belt carries a projection 8, which is adapted to strike the body 3, so as to force the same forwardly when the projection is on the upper stretch of the belt. j As the projection reaches the outer roller and starts to move downwardly, it

will disengage the body and a spring 9 connecting the body with the frame will snap said body back to its original position. As the projection comes around again, it will strike the body and move the same outwardly, so that the said body is moved outwardly at intervals.

Each of the stems 4- is provided with a groove 10, which receives a latch member 11. This member is pivoted intermediate its ends to the stem by the pin 12. The front end of said member is provided with a latch head 13 and its other end projects upwardly to form a trigger 14. A roller 14 is carried by said trigger to engage the pointed end of the frame. The front end ofthe groove is deep enough to admit the latch head 13 to permit the bobbin to pass over the same. A spring latch 15 is secured to each side of the frame in a position to engage the bobbin when the carrying member is in its innermost position.

The bobbin is placed 0n the spindle 4 of the irst turning member and the end of lthe thread secured to the side of the frame. The second member is then moved by the endless belt until its spindle strikes the spindie of the first member and pushes the same inwardly. This action will cause the roller on the trigger of the iirst member to engage the pointed end of the trame, thus depressing the latch head 13 to permit further movement of the parts to shove the spindle of the rst member through the bobbinand permit the spindle of the second member to enter the bobbin. This movement will continue until the spindle of the second member has passed entirely through the bobbin, shoving the spindle of the first membery ahead of it until the latch head 13 of the second spindle will engage the end of the bobbin and thus secure the bobbin on said second spindle. At this time the projection on the endless belt will release the second member so that the spring 9` of said second member will snap the same backwardly into its normal position, carrying ther bobbin with it. This will stretch the thread and then after the warps have been v moved the first member will advance, seize the bobbin from the second member and carry it back to the starting point. The thread is thus stretched again and after movement of the Warps the second member is advanced to seize the bobbin and this action is kept up to carry the thread back and forth through the Warps. Then latches l hold the bobbin against movement While the carrying members are at rest.

As myv invention relates Wholly to the means tor passing the Abobbin through the Warps, as shown in Figure 3, it is not thought necessary to illustrate or describe other portions or" the loom, as such parts are of the ordinarybr any desired construction. The invention can be applied to manually operated looms or to `power driven looms.

The Warps and the operating` means, as Well as the sley, have not been shown, as these parts are similar to those now used in the art.

What l claim is:-

l. A loom of the class described, comprising a pair of bobbin carriers, springs for holding the same in retracted position, an endless belt for each carrier, a projection on each belt for engaging the carrier to on said stem, a trigger for depressing said latch means, springs for holding the cari riers in retracted position, an endless belt for each carrier, a projection on each belt for engaging the carrier to project the same forwardly and means for rotating the belts.

3. A loom of the class described comprising a pair of bobbin carriers, each consisting of a body part and a stem movably mounted 1n the body part, spring means for holding the stem in'its outer position, latch means on said stem, a trigger for depressing said latch means, springs for holding the carriers in retracted position, an endless belt for each carrier, a projection on eac-h belt for engaging the carrier to project the same forwardly and means for rotating the belts.

In testimony whereof I affix my signature.

JOHN T. FITZPATRICK.
